有序相的大规模可控制造在纳米尺度上具有挑战性，但由于其良好有序的结构和化学性质是高级功能的关键，因此要求很高。在这里，我们展示了一个一般的纳米成型过程中的有序相原子扩散的基础上。所得的纳米线是单晶体，并保持其组成和结构，在其整个长度，我们解释了一个自排序的过程，从他们的窄吉布斯自由能。这种有序相的热机械纳米成型方法的多功能性、控制性和精确性为单晶生长提供了新的见解，并使其本身成为一种能够广泛用于纳米级和量子器件的技术。
Large-scale, controlled fabrication of ordered phases is challenging at the nanoscale, yet highly demanded as their well-ordered structure and chemistry is the key for advanced functionality. Here, we demonstrate a general nanomolding process of ordered phases based on atomic diffusion. Resulting nanowires are single crystals and maintain their composition and structure throughout their length, which we explain by a self-ordering process originating from their narrow Gibbs free energy. The versatility, control, and precision of this thermomechanical nanomolding method of ordered phases provides new insights into single crystal growth and suggest itself as a technology to enable wide spread usage for nanoscale and quantum devices.
